ATTACHING MACHINE.

Application filed August 3, 1923. Serial No. 655,518.

My invention relates to attaching machines, as those of the typedisclosed in Patent No. 1,382,762, Conner, June 28, 1921,

for securing a molded counter to the heelseat-portion of a turn-shoe.

In such machines, the counter to be attached is held in place upon ablock or extension-piece immovably under side of the die-block of anailing apparatus generally resembling the wellknown lightning heeler.This block enters between the upstanding sides of a counter, and holdsit in a definite relation to a jacked shoe when this has been pushedinto the nailing position beneath To change the relation between thecounter and heel-seat preparatory to attachment, so that the shoe shallbe of the correct size, the point at which the jack is arrested isdetermined by an adjustable back stop. The fixed character of theholding device for the shoe-part to be attached is disadvantageous insome respects, and an object of this invention is to provide, in anattaching machine, for a variation in the position of the part to beattached as it is held by the device, as by changing the effectivedimensions of the latter. More specifically, I efiect this changebothlongitudinally and transversely of the element. In connection withthe longitudinal alteration, it may be said that adjustment of the backstop of the abovementioned patent, to determine the location of acounter upon a shoe, is somewhat difficult for the operator, because theadjusting means is at the rear of the machine. I accomplish a similarresult by movement of a gage member through the counter-engaging wall ofthe holding device toward the rear of the machine, with means at thefront of said machine, convenient of access by the operator, foradjusting this gage member. The transverse adjustmentrenders the holdingdevice applicable to such objects as counters, which are without theusual trucks secured to their flanges and spacing the side walls aconstant distance apart. tucks omitted, as is sometimes desired bymanufacturers of turn-shoes, there is nothing to hold the peripheries ofthe counters in the proper relation to the outer edges of theheel-seat-portions of the shoes, the springsecured upon the thedie-block.

With the clips of the holding blocks tending to press the sides of thecounters closer together than they should be when secured upon theshoes. WVith the transverse adjustment of the hold-' ing device, whichmay be accomplished by gages movable through the engaging walls at theopposite sides of the device, the sides of each counter may be, in allinstances, correctly located with reference to the shoe to which it isto be attached.

One of the several embodiments which my invention may assume isillustrated in the accompanying drawings,

Fig. 1 being a side elevation, with parts in section, of the portions ofa counter-attaching machine more closely -co-operating with the work;

Fig. 2, an enlarged front elevation of the center of the die-blockandcounter-holding block I Fig. 3, a central vertical longitudinalsection through the counter-holding block; and

Fig. 4:, a full transverse section therethrough on the line 4.4i of Fig.3. i

There appear in the drawings only those portions of a counter-attachingmachine which are 111 direct association with the elements of thepresent 111VG111310I1. These include a die-block'lO mounted upon a frame12 and having in it vertical openings 14L to receive theattaching nailsor tacks. Entering these openings are drivers 16 depending from a topgrit 18 carried by vertically reciprocatory side rods 20; In horizontalways 22, carried by the usual pressure-applying mechanism, is a ack 24,shown as having upon it a lasted shoe S. This ack is movable 1n the waysfrom its outer position, in whlch the work is placed upon it, to thatillustrated in Fig. 1, in which the heel'seat-portion of the jacked shoeis alined withthe openings 1% in the die-block. Fixed in place upon theunder side of the die-block and having openings 26 registering with theopenings 14; is

a counter-holding block or extension-piece 28. The periphery of thisholding block has substantially the horizontal contour of a counterwhich is to be attached, having a side wall 30 curved similarly to theinterior of the counter, and a vertical breast-wall 32, which comesbetween the'spaced ends of the counter. Spring-clips 34c, 34, projectingCal over the wall adjacent to the breast-wall and adjustably mountedupon a transverse screw 36, press toward the blockan applied counter andserve to retain it in place. A spring-clip 37 depends from the die-blockat the backof the block 28, for engagement with the counter at thispoint. To permit this clip to co-operate properly with a gage memberhereinafter described, it should possess sutiicient yieldability toallow thecounter to be forced rearwardly to some extent. Mounted to movewith theja-ck is a back stop 38 carried upon the upper extremity of arod 40.

the sole to correctly locate the shoe beneath the block for cooperationwith the counter which is to be nailed upon it. 'The rod 40 is engagedbythe head of ascrew 42 threaded horizontally through a bracket securedto the frame and adjustable by means of .a nut 44 rotatable betweenspaced walls of the bracket. By turning this nut to advance or retractthe screw, the position of the back stop, and consequently the relationof the engaged shoe to the counter, may be changed.

The counter-holding block 28 is shown as fonmed in two sectionshorizontally divided, there being in one of these sections, preferaab-lythe upper, a groove extending centrally and longitudinally of the block.Arranged to slide in this groove is a bar 46 having projecting throughthe rear of the curved wall 80 of the block an end 48 furnishing .a backgage. Upon. the forward extremity of the bar is an upstanding lug-50, inwhich is a horizontal, threaded opening to receive a screw -52. Thisscrew carries flanges 54, 54 rotatable upon opposite sides of .a wall 55of the block. The head 56 of this screw lies outside the breast-wall 32,where it is directly in front of the operator and entirely clear of thework. Ordinarily, the initial adjustment to determine the relativelongitudinal relation between the jacked shoe and the counter which isto be secured to it would be provided for by the adjustmentof the backstop 88. The rear edges of the shoe-soles, however, vary considerably intheir extension against the portion of the upper which contacts withthe. back stop, bjecause, being in temper, they are likely to bedeformed. If, ha-vingbrought the heel-seat-portion of the shoe beneaththe block 28 and the .counter which it sup ports, the operatorobservesthat the vpoint of attachment of the counter will not be far enough backon the sole, a condition which would make the resulting shoe shorterthan the true size, he can remedy this by .adjust ment of the gage-bar46. To do this, he has only to turn the readily accessible head-56,forcing out the-end-portion 48, so that the counter is displacedsomewhat rearwardly This stop contacts with the rear of the jackedshoe-upper outside the edge off ect to be attached,

upon the block 28 until such counter is correctly located over theheel-seat. The attaching operation having been effected, the operatormay return the gage to its normal position.

Below the bar 46, adjacent to the breastwall 32, and extendingtransversely of the block 28, is a horizontal bore, in which are mountedopposite tubes 58, 58 having their closed, rounded ends outside theblock-wall 30 to act as side gages. The interiors of these tubes areoppositely threaded to receive similarly threaded portions of a screw62. Extending into the block, through the breast-wall 32, is a slotlying between the gage-tubes 58 "and receiving a flange or finger-piece64 secured at the center of the screw 62. The periphery of thisfinger-piece projects beyond the breast-wall, and is preferably-nur-le'd so that Y it may be turned conveniently by the op erator. Byrotating the-screw 62 by means of its finger-piece, the ends of thegage-tubes may be projected from or drawn into the openings through thewall 30 of the block, furnishing adjustable abutments against which theclips 34 may clamp the su ppono ed counter with its sides prope'nlyspaced to ,agree with the outside of the heel-seat-portion to which itis to be attached.

count of the position of the finger-piece 64, this adjustment of theends of the gagetubes may be varied readily by the operator when thesizes of the counters change.
